Hi and Welcome!
I have not used Dermatrans products specifically and am wondering what the "hook" is over any other compounding pharmacy. I found relief with one compounded topical around my surgical scar that had gabapentin and ketamine in it. Tried another with everything but the kitchen sink in it and didn't notice much. For what it's worth the one that was kind of sticky seemed to sit on the skin and not work as well. The helpful one was creamy and stayed creamy. Some products crystallize over time and then you can't rub it in. I think topicals definitely have a place but they are very dependent on the vehicle chosen, etc. I also found them to be fairly expensive. When I tried a new one I just had them make up the smallest amount possible so I wasn't overcommitted.
I don't know how helpful any of this might of been but it's all I got! I hope you find relief soon.
Sending Healing Love, Littlepaw.
